Этиология очаговой неврологической симптоматики у педиатрических пациентов с гемобластозами при проведении полихимиотерапии может быть разнообразной: цереброваскулярная патология (артериальный ишемический инсульт, интракраниальное кровоизлияние, тромбоз венозных синусов или их сочетание), инсультоподобная мигрень после лучевой терапии (stroke-like migraine attacks after radiation therapy, SMART), синдром задней обратимой энцефалопатии (posterior reversible encephalopathy syndrome, PRES), тромботическая микроангиопатия с вовлечением центральной нервной системы, токсическая лейкоэнцефалопатия, включая лейкоэнцефалопатию с инсультоподобным течением. Тактика врача-невролога во многом зависит от причин, вызвавших неврологический дефицит. Врачу необходимы знания не только клинической картины и особенностей течения основного заболевания, но и возможных осложнений, возникающих как вследствие самого заболевания, так и обусловленных проводимой терапией. Своевременная диагностика и корректная трактовка возникающих неврологических событий позволяют определить рациональную сопроводительную терапию. В статье приводятся истории болезни детей с острыми лимфобластными лейкозами и остро возникшим неврологическим дефицитом, с анализом их возможных причин. </p></abstract><trans-abstract xml:lang="en"><p>There are considerable variations in the reported incidence methotrexate-induced neurotoxicity in children with malignancies. The etiology of acute neurological deficit in pediatric patients with malignancies during polychemotherapy can be diverse: cerebrovascular disease (arterial ischemic stroke, intracranial hemorrhage, venous sinus thrombosis, or their combination), stroke-like migraine attacks after radiation therapy (SMART), posterior reversible encephalopathy syndrome (PRES), thrombotic microangiopathy, toxic leukoencephalopathy (include strokelike leukoencephalopathy). The tactics of a neurologist largely depends on the reasons that caused the neurological deficit. The doctor needs knowledge not only of the clinical picture and the characteristics of the course of the underlying disease, but also of possible complications arising both as a result of the disease itself and due to the therapy being carried out. Timely diagnosis and correct interpretation of emerging neurological events make it possible to determine rational accompanying therapy. The article presents case histories of children with acute lymphoblastic leukemias and acute neurological deficits, with an analysis of their possible causes. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>лейкоэнцефалопатия с инсультоподобным течением</kwd><kwd>токсическая лейкоэнцефалопатия</kwd><kwd>нейротоксичность</kwd><kwd>лимфобластный лейкоз</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stroke-like leukoencephalopathy</kwd><kwd>toxic leukoencephalopathy</kwd><kwd>lymphoblastic leukemia</kwd><kwd>neurotoxicity</kwd><kwd>children</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Inaba H., Pui C.H.
